Routing and Connecting Ductwork
Follow the guidelines below to maximize drying
performance and reduce lint buildup and
condensation in the ductwork.
NOTE: Ductwork and fittings are NOT included
and must be purchased separately.
• Use 4-in. (10 cm) diameter rigid or semirigid
metal ductwork.
• The exhaust duct run should be as short as
possible.
• Use as few elbow joints as possible.
• The male end of each section of exhaust duct
must point away from the dryer.
• Use duct tape on all duct joints.
• Insulate ductwork that runs through unheated
areas in order to reduce condensation and lint
buildup on duct surfaces.
IMPORTANT: Failure to exhaust the dryer
correctly will void the dryer’s warranty.
